Thanks Bob and David,
The XTICKLEN solution almost works - it just the enduser wants
tickmarks. Added to my woes is that I really want to stack three plots
or more. I though I could perhaps plot the bottom one first, get the
tickvalues (XTICK_GET) and the specify the tickvalues (XTICKV) but that
doesn't do it.
Hmmm.
Thanks anyway,
Ben
